Conforming High-Quality SVG Viewer says:

Color management via ICC profile support (i.e., the ability to support colors defined using ICC profiles).

This has been in SVG since 1.0, is implemented in Inkscape, used to be implemented in the Adobe and Corel viewers. That functionality (@profile etc) is now in CSS Color 4 while SVG2 references CSS Color 3.

Using color profiles is a good and useful feature and should be encouraged. Conforming High-Quality SVG Viewer is in any case a clearly optional feature, so doesn't impede progress to Recommendation. So my preferred option would be to keep the wording, and add an informative reference to CSS Color 4 in references.

Thoughts?
